As last year and the year before, I invite every HA.org members to answer a few questions. 920 persons take part to the same poll in 2007. And in 2008, a new record was broken with more than 1200 participants. I would thank the HA.org team who makes this score possible by giving to this poll a lot of visibility (it was pinned and appeared on HA portal during several weeks). I invite of course everyone to break it in the next months.

With all datas we gathered in the last year we now have nice and interesting curves:

____NB: To keep this first post short, I will post the links to previous polls and all exact datas a bit later.
